Today, however, crop genes are threatened by social and technological change such as human population growth, the use of new agricultural technologies, the development of new varieties, and the commercialization of agriculture. Gene banks have been successful in capturing much of the genetic diversity of crop species, but it is also essential that the environmental systems w 606 $aCrops$xGenetic engineering 606 $aCrops$xGermplasm resources 615 0$aCrops$xGenetic engineering. 615 4$aCrops$xGermplasm resources. 676 $a631.5233 700 $aBrush$b Stephen B.$f1943-$0248204 801 0$bAU-PeEL 801 1$bAU-PeEL 801 2$bAU-PeEL 906 $aBOOK 912 $a9910783411303321 996 $aGenes in the field$93822635 997 $aUNINA
